Waterproof shoe

ABSTRACT

A waterproof shoe has an outer skin, a twill layer, a rubber layer, and a lining. The twill layer is disposed on the outer skin. The rubber layer is disposed on the twill layer. The lining is disposed on the rubber layer.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a waterproof shoe. More particularly, the present invention relates to a waterproof shoe which has a rubber layer to prevent water from entering an inner interior of the waterproof shoe.

[0002] Referring to FIGS. 1, 2 and 2A, a first conventional waterproof shoe 20′ has a synthetic skin 21′, a lining 40′, and a twill layer 22′ disposed between the synthetic skin 21′ and the lining 40′. Since the synthetic skin 21′ is generally made of a waterproof material, the twill layer 22′ need not be made of waterproof materials. After a long period of usage, water will enter the first conventional waterproof shoe 20′ through capillarity.

[0003] Referring to FIGS. 3 and 3A, a second conventional waterproof shoe 20″ has an outer skin 21″ made of a cattle hide, a canvas, a flannelette or a fiber fabric, a twill layer 22″ disposed on the outer skin 21″, a polyurethane film 23″ disposed on the twill layer 22″, a waterproof bar 30″ disposed on a seam portion of the polyurethane film 23′, another polyurethane film 41″ disposed on the waterproof bar 30″, and a lining 40″ disposed on the polyurethane film 41″. The waterproof bar 30″ is made of a waterproof adhesive or a hot-melting adhesive. It is very expensive to use the polyurethane film, the waterproof adhesive or the hot-melting adhesive. If the waterproof bar 30″ is made of the hot-melting adhesive, the hot-melting adhesive is useless unless a certain pre-heating temperature is reached. Water will leak from a plurality of seaming apertures formed on the polyurethane film 23″. Water will leak from any seam portion of the second conventional waterproof shoe 20″ while a waterproof treatment is improper.

SUMMARY OF THE INVENTION

[0004] An object of the present invention is to provide a waterproof shoe which has a rubber layer to prevent water from entering an inner interior of the waterproof shoe.

[0005] Another object of the present invention is to provide a waterproof shoe which has a waterproof plastics layer to prevent water from entering an inner interior of the waterproof shoe.

[0006] Accordingly, a waterproof shoe comprises an outer skin, a lining, and a waterproof layer disposed between the outer skin and the lining.

[0007] In accordance with a first preferred embodiment of the present invention, a waterproof shoe comprises an outer skin, a twill layer, a rubber layer, and a lining. The twill layer is disposed on the outer skin. The rubber layer is disposed on the twill layer. The lining is disposed on the rubber layer.

[0008] In accordance with a second preferred embodiment of the present invention, a waterproof shoe comprises an outer skin, a plastics layer, and a lining. The plastics layer is disposed between the outer skin and the lining.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIGS. 4 and 4A, a first waterproof shoe 20 comprises an outer skin 21, a twill layer 22, a rubber layer 50, and a lining 40.

[0019] The twill layer 22 is disposed on the outer skin 21.

[0020] The rubber layer 50 is disposed on the twill layer 22.

[0021] The lining 40 is disposed on the rubber layer 50.

[0022] Referring to FIGS. 5 and 5A, a second waterproof shoe 2 a comprises an outer skin 20 a, a plastics layer 60 a, and a lining 40 a.

[0023] The plastics layer 60 a is disposed between the outer skin 20 a and the lining 40 a.

[0024] Since the present invention does not need seam portions, water cannot enter an inner interior of the waterproof shoe of the present invention. However, water will leak from seaming apertures formed on the polyurethane film of the conventional waterproof shoe and water will leak from any seam portion of the conventional waterproof shoe while a waterproof treatment is improper. The rubber layer and the plastics layer of the present invention are pre-formed into a shoe shape, so water leakage test will be performed to guarantee a waterproof quality of the present invention. The present invention need not use any waterproof adhesive nor any hot-melting adhesive in order to lower a manufacture cost. The present invention need not use polyurethane film in order to provide a soft lining.

[0025] The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention. 

I claim:
 1. A waterproof shoe comprises: an outer skin, a lining, and a waterproof layer disposed between the outer skin and the lining.
 2. The waterproof shoe as claimed in claim 1, wherein the waterproof layer is a rubber layer.
 3. The waterproof shoe as claimed in claim 1, wherein the waterproof layer is a plastics layer.
